Looks good!
My only thought of an "improvement" would be to use a lower profile bolt/screw. I'm sure those are plenty strong, so probably not likely to have a head break off, but I could see them possibly catching something.
Not sure exactly what I would be hauling that square head would make a difference, that’s the main path of tractor tires/tread.
I used galvanized 1/4 “ x 2” lag screws, hardware I already have, but for the front section, I have thought about using much smaller screws for like the bucket etc to slide if need be. It’s a equipment trailer, it’s going to get abused, even if I’m gentle with the unloading/loading, all that shit is just heavy, not much I can do, it’s not like
@tex lives near me, because you know tire shine would have already been applied to the spare and trailer tires,
